Ah, that’s my mistake. I originally saw the issue on an older FreeBSD release and missed that the code had changed subtly when I looked up the version in head. r328552 fixed this issue already Thanks for the sanity check. Sent from my iPhone > On Oct 2, 2019, at 6:51 PM, 神明達哉 wrote: > > At

Hi, I made a small change to usr.sbin/arp/arp.c by replacing gethostbyname to getaddrinfo. This is the first time I used phabricator and also my very first commit so my changes are really minor. [1] Could someone possibly review it? [1] https://reviews.freebsd.org/D21585 Kind Regards, Mihir ___
